“…The cutting layer of the workpiece fractures due to external load, forming chips. The local temperature of the tool surface rises, and the chips formed easily adhere to the tool surface, leading to a reduction in the tool's service life [22][23][24].…”

Titanium alloy material has physical properties such as low thermal conductivity, high hardness, and surface resilience, which are prone to problems such as large milling force, low machining efficiency, and poor surface quality in processed products during dry milling. This document details our process of isolating micro-textures from biological structures, applying them to cutting tool surfaces to create micro-texture milling cutters, and employing this micro-texture technique to reduce friction and prevent wear on these cutters. According to the milling dosage and the installation position between the tool and the workpiece, the effective working area of the cutting edge of the ball-end milling cutter is calculated. At the same time, a self-lubricating cutter was constructed by using a laser to process micro-textures and filling solid lubricant inside the micro-textures. An analysis was conducted to compare the milling efficiency of bionic microtextured cutters in both dry and micro-lubricated environments. It was found that the self-lubricating tool promoted a 3% to 5% decrease in milling force, a reduction in the coefficient of friction, a high surface finish of the machined workpiece, and an alleviation of chip sticking at the edge area.

“…The issues of texturing the contact surfaces of cutting tools subjected to high-intensive wear and designed for machining products made of hard-to-cut materials are currently the focus of the attention of leading research groups [1][2][3]. Texturing of a cutting tool is the formation of a three-dimensional specific microrelief on its surfaces in the form of various variations of grooves, wells/holes, protrusions, etc.…”

The article describes the technological principles of electrical discharge machining of the surface layer of SiAlON dielectric ceramics based on the artificial creation of conductive conditions of the ceramics’ surface layer, making it possible to form microtextures such as microgrooves and microwells/holes. It has been established that the processing stability between the electrode tool and the ceramic insert is increased by the deposition of electrically conductive coatings to ceramic inserts and supplying finely dispersed ZrO2 and TiO2 assisting powders into the interelectrode gap merged in a dielectric medium. The resistance tests carried out have shown that the use of compounds based on hard thermostable nitrides of refractory metals (AlCrTiNbSi)N and TiN-(AlCrTi)N as coatings with subsequent microtexturing provides a mutually reinforcing effect and makes it possible to increase the wear resistance of ceramic inserts up to 2.6 times when turning an Inconel 718 heat-resistant nickel alloy.

“…In the literature, there have been published works on texturing the surface of cutting tools, in which their effect on friction and wear were studied [ 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 ]. These studies showed that this approach allows for improving the tribological properties in the tool–chip interface, reducing the machining temperature, the rate of tool wear and the cutting forces, and consequently obtaining an increase in machining productivity [ 25 ].…”

The Influence of Surface Texturing of Ceramic and Superhard Cutting Tools on the Machining Process—A Review

et al. 2022

Machining is an indispensable manufacturing process for a wide range of engineering materials, such as metals, ceramics, and composite materials, in which the tool wear is a serious problem, which affects not only the costs and productivity but also the quality of the machined components. Thus, the modification of the cutting tool surface by application of textures on their surfaces is proposed as a very promising method for improving tool life. Surface texturing is a relatively new surface engineering technology, where microscale or nanoscale surface textures are generated on the cutting tool through a variety of techniques in order to improve tribological properties of cutting tool surfaces by reducing the coefficient of friction and increasing wear resistance. In this paper, the studies carried out to date on the texturing of ceramic and superhard cutting tools have been reviewed. Furthermore, the most common methods for creating textures on the surfaces of different materials have been summarized. Moreover, the parameters that are generally used in surface texturing, which should be indicated in all future studies of textured cutting tools in order to have a better understanding of its effects in the cutting process, are described. In addition, this paper proposes a way in which to classify the texture surfaces used in the cutting tools according to their geometric parameters. This paper highlights the effect of ceramic and superhard textured cutting tools in improving the machining performance of difficult-to-cut materials, such as coefficient of friction, tool wear, cutting forces, cutting temperature, and machined workpiece roughness. Finally, a conclusion of the analyzed papers is given.
